Susan Winter undertakes an expedition to a remote area of Mexico, hoping to find her fiance, Bruce Barton, whos plane-crashed there some time ago. The area is suspected to have a good supply of uranium, so Susan has promoted this to wealthy Martin Melville to get money for her expenses. In addition to Melville, she is accompanied by guide Russ Bradford and pilot Lee Brand in his small-engine craft. But the plane crashes, stranding the four in an isolated valley, which they soon discover is highly radioactive and inhabited by mutated life forms - giant insects, enormous lizards, and a 25-foot-tall human male with a deformed face, just one eye, and only brute animal instincts to feed and protect its turf...

Though much of the action takes place in two different canyons, all scenes for both were shot in the fabled Bronson Canyon; the famous cave was used in the "second" one. See more »


When Russ is trying to get Susan to realize that the giant is her missing fiancé Bruce, he says that with growth accelerated by radiation, the scar above Bruce's left eye would eventually grow and cover it over. Unfortunately, the scar tissue covers the giant's right eye. See more »

The Cyclops (1957) **
24 October 2010 | by (U.S.A.) – See all my reviews

** out of ****

Fun 1950s silliness from Bert I' Gordon, as a woman (Gloria Talbott) hires a team of three men to fly into a remote area of Mexico to help find her missing fiancé who disappeared a few years earlier. What they discover is a forsaken land contaminated by radiation which has produced giant animals and reptiles, as well as a raging 25-foot tall bald man with one eye.

The highlight of this show is Lon Chaney as a punchy hot-head on the expedition, who cares more about finding uranium than he does saving a man's life. The monster itself becomes annoying with his consistently dubbed roars and growls.
